As most people don’t know, Southern California has other faults besides The San Andreas fault. On Wednesday night a weak earthquake was felt across the Los Angeles Basin, from Santa Monica to Long Beach. It occurred at 10:40 pm, the epic center was close to the Newport-Inglewood/Rose Canyon fault system that was responsible for the 1993 Long Beach earthquake that killed 120 people. The idea that the fault could produce more powerful earthquakes than the one that occurred in 1993 has been growing.
